wecs.repl module

class wecs.repl.Interpreter(*args)

Bases: code.InteractiveConsole

runline(line)

showsyntaxerror(filename=None)

Display the syntax error that just occurred.

This doesn’t display a stack trace because there isn’t one.

If a filename is given, it is stuffed in the exception instead of what was there before (because Python’s parser always uses “<string>” when reading from a string).

The output is written by self.write(), below.

runcode(code)

Execute a code object.

When an exception occurs, self.showtraceback() is called to display a traceback. All exceptions are caught except SystemExit, which is reraised.

A note about KeyboardInterrupt: this exception may occur elsewhere in this code, and may not always be caught. The caller should be prepared to deal with it.

showtraceback()

Display the exception that just occurred.

We remove the first stack item because it is our own code.

The output is written by self.write(), below.

write(output_string)

Write a string.

The base implementation writes to sys.stderr; a subclass may replace this with a different implementation.
